3 Acute Respiratory Failure Online Quiz Questions

True or false: Acute respiratory failure can involve inadequate oxygenation, inadequate ventilation, or both.

What PaO₂ threshold, in mm Hg, can support a diagnosis of acute respiratory failure when the value is below that threshold?

A patient with pneumonia develops diffuse lung opacities and a PaO₂ of 52 mm Hg despite supplemental oxygen. Which type of respiratory failure is most likely, and what mechanism may be contributing?

Which conditions are identified as possible causes of hypoxemia? Select all that apply.

With acidemia, what PaCO₂ threshold, in mm Hg, can support a diagnosis of acute respiratory failure when the value is above that threshold?

An ABG shows pH 7.28, PaCO₂ 60 mm Hg, and HCO₃⁻ 26 mEq/L. Which interpretation best fits these results?

True or false: A PaCO₂ value should always be interpreted without considering the patient’s baseline or prior results.

A patient has a low oxygen saturation and suspected acute respiratory failure. Which approach best evaluates the problem while initial treatment begins?

Which findings in a patient with worsening shortness of breath can signal respiratory deterioration and call for prompt reassessment? Select all that apply.

True or false: Needed oxygen should be withheld from a patient solely because the patient’s CO₂ is elevated.

A patient with a COPD exacerbation is alert and cooperative but has respiratory distress and acute respiratory acidosis. Which treatment may be appropriate if there are no contraindications?

A mechanically ventilated patient suddenly becomes hypoxemic and distressed. Describe the nurse’s immediate response, including patient assessment, equipment checks, and escalation.

A PaO₂ below what threshold, in mm Hg, can support a diagnosis of acute respiratory failure when interpreted in clinical context?

A patient with worsening shortness of breath is restless, diaphoretic, tachypneic, and using accessory muscles, then becomes confused. What is the priority response?

A patient has low oxygen saturation and suspected acute respiratory failure. Which approach best evaluates the problem while initial treatment begins?

A patient becomes hypoventilated after receiving an opioid. If respiratory failure develops, which classification and mechanism best fit?

A patient with a COPD exacerbation is alert and cooperative but has respiratory distress and acute respiratory acidosis. What type of respiratory support may be appropriate if there are no contraindications?

A mechanically ventilated patient suddenly becomes hypoxemic and distressed. What should the nurse do first?
